ABSTRACT

A packaging bag includes two long sides, two narrow sides, a top side or roof surface, a bottom side produced from one or more layers of plastics material foils, and a carrying handle including a single-part or multi-part plastics material strip arranged to pass around the packaging bag in a region of the top side.

RELATED APPLICATIONS

This is a §371 of International Application No. PCT/EP2010/051120, with an international filing date of Jan. 29, 2010 (WO 2010/091968, published Aug. 19, 2010), which is based on German Patent Application No. 20 2009 002 180.7, filed Feb. 16, 2009, the subject matter of which is incorporated by reference.

TECHNICAL FIELD

This disclosure relates to a packaging bag having two longitudinal sides, two narrow sides as well as a top side and a bottom side, produced from one or more layers of plastics material foils, as well as having a carrying handle.

BACKGROUND

Different packaging bags are known. However, they often have problems with regard to the carrying handle.

The carrying handle is either integrally molded, as a result of which, however, material consumption is then not inconsiderable. In addition, press cuts have to be provided to form a handle aperture or to give the desired shape to the carrying handle itself.

However, strip-shaped carrying handles which have to be attached in an extra processing step are also known.

The two variants also have the problem that the handles make printing in the region thereof difficult or they even prevent it. Valuable advertising surfaces on the packaging bags are lost.

In addition, the carrying handles impede the sight of the top side of the packaging and make removal of the contents from the packaging bag difficult.

Handle apertures punched into the packaging bag are rejected as they damage the packaging and there can be no guarantee that the packaged product is protected against contamination.

Consequently, it could be helpful to create a packaging bag with a handle which does not have the aforementioned disadvantages.

SUMMARY

I provide a packaging bag including two longitudinal sides, two narrow sides, a top side or roof surface, a bottom side produced from one or more layers of plastics material foils, and a carrying handle including a single-part or multi-part plastics material strip arranged to pass around the packaging bag in a region of the top side.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 shows a diagrammatic side view of a packaging with carrying strips pulled up.

FIG. 2 shows a diagrammatic view of a narrow side of the same packaging with carrying strips.

FIG. 3 shows a diagrammatic illustration of another packaging with carrying strips not yet pulled up.

DETAILED DESCRIPTION

I provide a single-part or multi-part plastics material strip arranged to pass around the packaging bag in the region of the top side or roof surface.

Consequently, a carrying handle is created which is easy to attach, but nevertheless neither makes difficult removal of the packaged product nor impedes the sight thereof. In addition, printing on the sides can be extended.

It has also proven very advantageous when the plastics material strip is welded to the packaging bag at two opposite sides of the packaging bag.

This means that the plastics material strip that functions as a carrying handle can be attached in a secure manner. The load distribution is at least approximately even.

At the same time, it has proven very advantageous when the welding is realized in a ring-shaped or planar manner, namely in a circular or oval manner. This ensures that the welding has a secure hold even in the case of variable load directions.

Further advantageously, the welding is arranged in the middle of the narrow sides between the longitudinal sides. This means that it is very comfortable to carry.

It has also proven very advantageous when the welding is effected together with formation of a seam of the packaging bag. This means that no separate processing step for fastening has to be carried out.

Further, a plastics material foil strip is arranged which is welded to the packaging bag on each narrow side.

This means that the foil strip is distributed circumferentially and can be gripped very easily.

At the same time it is very advantageous when the two foil strips are connected to each other at the ends thereof. This improves the stability and durability of the foil strips even more.

Advantageously, printing over parts of or all-over the surface is also provided on the sides on the packaging bag.

This opens up a large advertising surface on the packaging.

It is also very advantageous when an unloading opening is provided at the top side and/or at one side of the packaging bag.

The packaged product can be removed very easily through the unloading opening.

A very advantageous feature is also provided when the foil strip projects in part above the packaging towards the top side. This means that the foil strip can be easily gripped.

It has also proved extremely advantageous when the foil strip is attached at least in sections along the longitudinal sides of the packaging bag. This avoids the foil strips being inadvertently pulled up.

At the same time it is very advantageous when the foil strip is separable by a perforation or tear-line. This achieves fastening that is secure, but nevertheless easily separable.

It is also extremely advantageous when the foil strip is formed from a single-layer or multi-layer plastics material foil. This means that a particularly durable foil structure can be created for the foil strip.

Another very advantageous feature is when the width of the foil strip is between 20 and 80 millimeters, preferably between 40 and 60 millimeters. With a width of this type, the foil strip does not cut unpleasantly into the hand of the carrier, but it is nevertheless very light and saves on material.

Turning now to the Drawings, the reference 1 in FIG. 1 is given to a packaging bag 1 which has two longitudinal side walls 2 and 3, two narrow side walls 4 and 5, a bottom 6 and a roof surface 7. The packaging bag 1 is formed from a foil portion 8, which is folded such that the roof surface 7 is formed and the longitudinal side walls 2 and 3 are arranged hinged thereto. The packaging bag 1 is closed at the bottom. The side edges of the foil portion 8 are welded to each other in the region of the narrow side walls 4 and 5. The bottom 6 is closed once the packaging bag has been filled.

An overprint 12 is provided on the side walls 2, 3, 4 and 5. A further overprint 13 can be provided on the roof surface 7. An unloading opening 14 can also be provided in the roof surface 7. However, it is also conceivable to provide the unloading opening 14 in a side wall, as it is shown in FIG. 3.

A foil strip 10 is welded-on at the edges 9 between narrow side walls 4 and 5 and the roof surface 7 in the region of the narrow side walls 4 and 5. The weld point is formed in an oval.

In FIGS. 1 and 2, the foil strip placed around the packaging bag 1 is pulled up and thus forms a carrying handle.

In the not-pulled-up state, the foil strip 10 is placed around the edges between the side walls 2, 3, 4 and the roof surface 7 and thus impedes neither the overprint 12 on the side walls 2, 3, 4 and 5, nor the overprint 13, nor the unloading opening 14.

The foil strip 10, in this case, can jut out beyond roof surface 7 so that it is easier to grip.

The packaging bag 1 can be produced from a single-layer or multi-layer plastics material foil. PE, PET, PP, PVOH, EVOH, PLA and others are conceivable as materials for this. It is conceivable, in particular, that renewable raw materials and/or biologically degradable raw materials are used.

The foil strip 10 can also be realized with one or multiple layers and can be produced from the same materials as the packaging bag.

Especially when comparatively heavy products are packaged in the packaging bag, it is possible to produce the foil strip 10 from sturdy material.

The weld point 11 can be realized in a planar or ring-shaped manner and at the same time can be round or oval. A round or oval structure provides an even introduction of force.

The foil strip 10 can be realized in one part or in multiple parts. It is conceivable, for example, for two part portions of the foil strip 10 to be placed on the front and rear side of the packaging bag 1 and then when the packaging bag 1 is welded shut, the two parts of the foil strip 10 to be welded to the packaging bag 1.

The two part portions of the foil strip 10 are interconnected when separated off

However, it is also conceivable for the two part portions of the foil strip 10 to be welded onto the packaging bag 1 separately at first. Further welding can then be effected when the packaging bag 1 is welded shut or separated off.

The surface of the side walls usable for printing is enlarged by the development and arrangement of the foil strip 10. The white region at the transition between side wall and roof surface 7 can be made smaller.

It is conceivable for the foil strip 10 to be connected to the packaging bag 1 also by bonding or sealing.

It is equally conceivable for the foil strip 10 between the weld points 11 to be fastened to the packaging bag to be still detachable.

A perforation or tear-line can be provided, ensuring the foil strip 10 has a secure hold, but nevertheless enabling easy detachability, thereby ensuring that the foil strip is not pulled up in an unintentional manner.
